. Sliding-Door Fastenings, of which the following is av specification.

The invention will be described with special reference to the sliding doors used on freight o r'iboX cars, but is `equally applicable tothe sliding' doors used inware.- Y

houses and similar buildings. lThe usual method of fastening car'ldoors isto provide a lock and a seal, which are applied to the front edge of the door. Such fasteners have the defect that it is comparatively easy inv many cases to gain access to the carat the back edge of the door without disturbing the seal. Devices havebeen proposed -which overcome this difficulty to a Vynffflntel`- 01 less egitent, but they are complicatedand expensive. y ,y

The main object is to provide an attachment that willlock the door eectively at the front and the back edges, and which will at the same time be simple to operate and inexpensive.

Another object of the invention is to provide an efficient and simple method of closing the space between the edge of the door and the wall of the structure to make the `door fire-proof, and to seal the door against other destructive elements. l

The invention further contemplates the attainment of all of the above mentioned objects in a single structure. Other more specific objects will appear in the following descriptions.

The accompanyingv drawings show adoor en'lbodying the various features of the inven-v Figure 1 is an elevation of a sliding door on a boX car showing the location of the various parts of the device.

Fig. 2 is a perspective view showing more clearly the operation of the parts of the device which lock the rear edge of the door.

Fig. 3 is a modification of the device shown in Fig. 1, to include a fire-proof .fea-

ture.

. mentarily, provided Vwith a door 2, having THOMAS BAKER,

Fig. 4 is a horizontal section. on Vthe line attached to its upper edge brackets 8, carrying rollers 4, adapted to run on track 5. On the` front edge of the door one or more bolts orbars 6 are securely fastened to the door. .O n the frame of the ldoor one or more sockets 7 aresecurel-y fastened. When the door 2` is closedfby slidingto the left, bolt 6 enters the socket j and thereby automatically locks the front edge of the door against up and down motion, or in and ont motion. Itis also to be noted that the door may be opened without the previous'releasingof any device at the front edge of the door. l Y

In Fig. 2 is shown a plate 8 securely attached to the car body adjacent tothe backedge of the door when closed. Hinged to back vedge of the door. On top of plate 12 is mounted a .plate 13 having a groove or seat portion 14, adapted to receive a bolt 15.

Bolt 15 has on its outer end a locking arm '16. The bolt is Vmounted to rotate and in one position of bolt 15,.the arm 16 swings over and locks plate 9 against the edge of the door 2 and over the projections 11. The

other end of bolt 15 has an actuating arm 17,

which projects through an opening 18 in seat 14. The arm 17 of bolt 15 has near its ylower end an eye 19which, in the locked position (the position shown in all the figures), is opposite the eye 2O in the end of a pin 21, fastened to the door 2. Eyes 19 and 2O are adapted to receive the wire of a seal 22 when the device is in thc locked position, and thus prevent the opening of the door 2 unless the .seal 22 is broken.. The end of the actuating arm 17 extends beyond pin 21, and provides a convenient handleV to rotate bolt 15 until the arm 17 assumes a position in which locking arm 16 clears plate 9, so that it is free to turnagainst the body of the car. A slot 23 in seat 14 is provided into which arm 17 12 extends slightly beyond the edge of the door 2. When it is desired to open the door the lower end of arm 17 is grasped turned to the upright position, pushed to the right and thus enters the slot 23 and with con,`

tinued pressure the projection 17 Will move.

the door and turn plate 9 againstlthe car body and allow the door to open, so that the door is opened by a'single operation.

i 4, parts 27, 28, 29 and 30 correspond to parts .13, 15, 21 and 11 in Fig. 2. Attached tothe bodyvof the car is plate 31, which may extend the full length of the car door. Hinged to plate 31 is another platef32, which also extends the full *length of the car door, Plate 32 corresponds to plate 9 and operates along with theV parts 27, 28, 29 and 30 in'a manner exactly corresponding to the operation Lof the corresponding parts in. Figs. 1 and 2. By having the-plate 32 extend the full length of the carV door'the opening betweenthe car door and the body of the car is completely closed against sparksor other agencies harmful to the contents of the-car. Such protectionlis particularly valuable for earsV carrying explosives or other inflammable materials.`

vThere maybe attachedto the varm 17 an insignia o1' marker in the form of'plate 33 bearing a shield or other vdesignation to show that the car is sealed and protectedl and af` ford a deterrent influence to preventtam- .peringwithlfthe car.

What I claim is:

at the rear ofthe door, the hinge pivot being substantially vertical, so that Vthe hinged inelnber swings againstthe. rearledgefof the door, the rear edge ofthe door having projections in the plane of the doom-interlocking with the'hnged member, and means lon the door forlockingthe hinged=me1nber plate to-hold itrfin'engagingfposition, and

v1. A fastening for sliding doors, consist. ing of a hinged member on they door frame sealingflneans, holding the" bolty ini engagei l nientwith thefplate.- 1
